Alcohol use disorder is characterized by a problematic pattern of alcohol use that gets in the way of life. Various studies have shown that there is a strong genetic risk to AUD and it is about 50% inheritable, making it three to four times more likely for a biological child of a person with AUD to develop the same disorder. It’s a common question, especially for those who’ve seen family members struggle with alcohol use. Science has some answers, and understanding the role of genetics can help you make informed choices about your relationship with alcohol. If alcohol addiction runs in your family or you’re concerned about your drinking habits, understanding these factors is the first step toward prevention or recovery.
Alcoholism: Top 10 Health Questions Answered
- A comprehensive review by the University of Cambridge, which analyzed 12 studies involving twins and adopted children, found that genetics accounts for about half of the risk for alcoholism.
- The child of a person with AUD is more likely to suffer from AUD since alcohol dependence and consumption level are partly inheritable traits, but it doesn’t necessarily mean that they will inevitably develop it later on.
- She said those larger samples of individuals with and without a diagnosis of alcohol dependence will be key to future discoveries about genetic contributions to alcoholism.
- However, when someone has a high tolerance, it can heighten the susceptibility of the disorder.
- But when it comes to more complex human features, the connection to our genes is less clear.

It’s crucial for regulatory bodies to monitor and control such influences, ensuring that they don’t exacerbate the substance use disorders already prevalent in society. Recent research from Indiana University has shed light on the significant role genes play in the development of alcohol use disorders (AUDs). Now, we enter an exciting time where genetic and environmental studies promise great strides for the understanding of our human genome and real changes in clinical care. While genetics play a is alcoholism genetic role, environmental factors are equally important in determining whether someone develops alcohol addiction.
Environmental Factors That Contribute to Alcohol Addiction
- While there are no specific tests that detect the genetic prevalence of AUD ahead of time, there are several tests, such as the Alcohol Use Disorders Identification Test (AUDIT), to help determine whether you have it currently.
- But now some of the work that we’re doing in Boston Children’s with my colleague Ryan Doan, is revealing that there are quite a few of those more rare changes to the DNA that are also contributing to ADHD in some families.
- Research estimates that the genetic factor contributes to your odds of developing alcoholism by 40% to 60%.
Alcoholism has a substantial impact on both mental and physical health and can present different features among affected individuals. Due to this, the mechanisms and possible causes of alcoholism cannot be as easily identified as diseases such as hemophilia, which presents clear physical symptoms. But in the decades since Angier’s article, scientists have made strides in figuring out the mystery of what really underlies this unique disease. Other risk factors for developing AUD are mental illness like depression, drinking from an early age, and experiencing a traumatic event or events.
Treatment Options for Alcohol Addiction
In their study, the Yale team discovered that the risk genes were correlated to changes in certain brain regions. This finding suggested to researchers that the risk variants promoted certain brain pathways that contribute to the development of behavior patterns and disorders. Studies suggest that genetics account for 40% to 60% of a person’s susceptibility to alcohol addiction. Specific genes influence how the body processes alcohol and how it impacts the brain’s reward system. Ultimately, while family history and genetics can elevate the risk of AUD, they do not guarantee its occurrence.
Is Alcohol Use Disorder (AUD) the Same Thing as Alcoholism?
Hereditary factors often overlap with environmental influences, such as growing up in a family with a history of alcohol use disorder. Children raised in these alcoholism symptoms environments may not only inherit a genetic predisposition but also learn behaviors and coping mechanisms that increase their risk of developing AUD. This interplay underscores how hereditary and genetic components are closely linked but not always a dictator of AUD.
Levels of Care
So, as I sat in a big, packed hotel conference room listening to Dr. Anne Arnett talk about her work on genetics and ADHD, I felt a surge of joy. Luckily, Dr. Anne Arnett, a scientist at Boston Children’s Hospital and assistant professor of pediatrics at Harvard Medical school, was kind enough to brave a chilly, windy outdoor recording. In this conversation, she help us understand more about what we know (and what we don’t) about ADHD and genetics. National Toxicology Program concluded that consuming alcoholic beverages is a known human carcinogen.
“We know now that it was only a first step of a very long road of complex genetics,” said Renato Polimanti, a colleague of Gelernter at the Yale School of Medicine. In contrast to Angier’s conclusion that AUD is decided by the environment, scientists have since found multiple genetic players. « A family history of AUD increases the risk of a biological child suffering from AUD. The inheritance is about 50%, ranging from 40% to 60%. »
